FIELD OF THE INVENTION

The subject application is directed toward devices which extract pulpand juice as well as other constituent components from foods such asfruits and vegetables.

BACKGROUND OF INVENTION

Devices to disintegrate foods are very common today. Such devicesinclude, but are not limited to: juicers, blenders, and food processors.Essentially, these devices feed foods, including, but not limited to,fruits and vegetables, into a machine which mechanically disintegratesthe foods. Many of these devices have feed chutes. Also shared in commonby many of these devices is a rotating shredder element which chopsand/or grinds the foods.

One of the most common devices to disintegrate foods is the centrifugaltype juicer. These devices typically have a generally vertical feedchute which is open at the top and terminates at its open lower end justabove a motor powered horizontal shredding disc. Most of these shreddingdiscs are simply flat plates with sharp protrusions facing upward. Asfood is fed through the feed chute, it is pushed by gravity and/or by ahand powered pusher plunger placed facing downward at the top of thechute. These pushing forces propel the food onto the top of theshredding disc where the sharp upward facing protrusions grind apart thefood.

The shredded food is propelled outward radially from the center of theshredding disc by centrifugal force, until the shredded food hits afilter screen which is formed in the shape of an inverted truncated conewith its broader face being open and directed upwards. The truncatedcone is attached to the shredding disc along the cone's lower smallerface which is positioned resting against the outer perimeter of theshredding disc.

The rotation of the truncated cone filter screen through centrifugalforce, forces liquids, including juices, through the filter screen andinto a collection vessel, while simultaneously directing solids, such aspulp, to be propelled diagonally upward, outward, and over the upperperimeter edge of the open broader face of the truncated cone, where itis collected in a collection bin.

The net result of the above actions is the separation of liquids fromsolids within the foods.

These centrifugal juicers are inexpensive to produce. They also producejuice relatively quickly when compared to other designs.

However, typically they have several shortcomings.

To begin with, their truncated conical filter screens load up veryquickly with pulp which reduces their efficiency and is very difficultto clean, especially if the pulp clogged in the screens is not cleanedimmediately after juicing.

Also, even though there have been great strides in recent years inincreasing the size of the feed chutes, and thus decreasing foodpreparation time because foods no longer have to be cut to a small sizecompared to using a small feed chute, some food cutting preparation isstill required for larger foods.

Ironically, the new larger feed chutes found on newer centrifugaljuicers, which offer convenience to juicer users, also introduce asafety hazard to the same users because the size of the new chutes islarge enough to allow a child's hand to pass through the chute and intocontact with the rapidly rotating shredder disc.

A further typical disadvantage of current centrifugal juicers is that aliquid collecting receptacle must be placed adjacent to the juicer tocatch juices immediately as the juice is produced, because these juicersgenerally do not have any onboard ability to collect and store juices.

These juice collecting receptacles usually have the disadvantage thatfresh juices collected within them typically separate within a fewminutes thus losing their fresh taste and pleasing appearance. This isbecause there is generally nothing within or about such receptacles tomix and/or agitate the freshly made juice to prevent separation fromoccurring or to mix the juice once separation has occurred.

Further, many centrifugal type juicers have low pour spouts which don'tpermit normal height glasses to be placed beneath them. Such juicersmust rely on resting on a wood block or other such pedestal to fillnormal height glasses, or the user must find and use a specialreceptacle which has a low height upper rim which can fit below the pourspout.

Those juicers that have pour spouts which are high enough to fill anormal height glass, are generally difficult to store due to thejuicer's height.

In addition, many juicers force their users to waste precious timebefore removing their glass while waiting for the juicer's pour spoutsto stop dripping after juice has been dispensed.

Another typical disadvantage of current centrifugal type juicers is thatparticles of the foods fed down the feed chute can hit the fast spinningshredding disc and be thrown back at high speed through the feed chuteat the juicer user causing messes on the user and/or adjacentcountertops, as well as resulting in a safety hazard to the juicer userfrom being hit by fast-moving ejected food particles.

Centrifugal type juicers also can get jammed on food because there is noway to move the food around in relationship to the shredding disc. Theonly option offered by most centrifugal type juicers to free food jammedwithin the feed chute is to push down harder on the juicer's pusherplunger. Such pushing may relieve the problem, or it may compact thefood within the chute and make the problem worse.

Juicing efficiency within juicers is always an issue because it affectsthe cost of juice produced. Centrifugal juicers are only moderatelyefficient when compared with other designs, because they leavesignificant amounts of juice and moisture within their waste. Thisefficiency is reduced as mentioned earlier when the truncated conefilter screen becomes filled with pulp. Efficiency is also lost becauseshredding of the food within a centrifugal juicer takes place in onlyone stage so any juice which is not extracted at this first and onlystage is permanently lost.

Many of the disadvantages of centrifugal juicers are shared in commonwith other food preparation devices such as, but not limited to,blenders and food processors. Such disadvantages include, but are notlimited to, issues involving feeding foods into the device, extractingprocessed foods from the device, the height of ejector chutes, as wellas other safety, use and storage issues.

The example embodiments described herein are designed to address manyknown problems, including, but not limited to, those listed above, foundin many of today's food preparation devices. Some of the embodimentsdescribed herein also go beyond this to suggest improvements on thefunctionality of food preparation devices.

DETAILED DESCRIPTION OF EXEMPLARY PREFERRED EMBODIMENTS OF THE PRESENTINVENTION

Several preferred embodiments of the subject application are describedherein. Each alone or in combination addresses problems and designopportunities found in current food preparation devices. Except asnoted, preferred embodiments are illustrated as centrifugal type juiceextractors.

FIGS. 1 through 12, and including FIG. 9 enlargement, 9 a, and FIG. 12enlargement, 12 a, are perspective views that show mechanisms to raisepour spout heights for easy dispensing of liquids while simultaneouslyoffering compactness during storage. In general these designs raise thefood preparation device using a support member which can telescope overthe main body to a more compact configuration to reduce the spacerequired to ship and store the food preparation device.

FIGS. 13 through 21 show various pour spout configurations. FIGS. 13,14, 15, 16, and 19, including FIG. 13 enlargements, 13 a, 13 b, and 13c; and FIG. 14 enlargements, 14 a, 14 b, and 14 c; and FIG. 15enlargements, 15 a, 15 b, and 15 c; and FIG. 16 enlargements, 16 a, 16b, and 16 c; and FIG. 19 enlargements, 19 a, 19 b, and 19 c are allperspective views. FIGS. 17, 18, 20, and 21 are cross-sections asindicated in the forward perspective views. In general, these pour spoutconfigurations have a liquid flow control valve to turn on and off theflow of liquid from the device's internal liquid collecting vessel. Eachliquid flow control valve along with the configuration of each liquidegress passage help quickly terminate liquid flow from the devices andthus reduce the time needed before a glass or other liquid collectingreceptacle can be removed from below the spout without resulting in thespout dripping on a countertop.

These pour spout configurations also allow the liquid flow control valveto be activated and deactivated using movement of a glass or otherliquid collecting receptacle placed beneath them.

Because these pour spouts can completely block the flow of liquids fromthe devices, these pour spouts also may allow storage of liquids withinthe embodiments before the liquids are dispensed into a glass or otherliquid collecting receptacle, thus eliminating the need to have a liquidcollecting receptacle positioned below the liquid egress passagewhenever juicing takes place.

FIGS. 22 through 28 show centrifugal juicers with shredder discconfigurations that have central shredder disc configurations designedto hasten and make more efficient shredding. Each shredder disc, exceptfor the one shown in FIG. 28, is shown with its inverted truncated coneshaped filter element.

Exemplary Preferred Embodiment One

Referring to FIGS. 1 through 3, food preparation device 100 is supportedby base 102. Food preparation device 100 may be a centrifugal type juiceextractor as illustrated, or it may be an alternative such as by way ofa non-limiting examples, a food processor or blender or other type offood processing device. Base 102 has generally vertical sidewalls 106 atits periphery. Generally horizontal partition 104 is asymmetricallyplaced vertically within vertical sidewalls 106 and divides the spacewithin vertical sidewalls 106 into 2 concavities, one being shallow andthe other being deep and occupying most of the interior space defined bysidewalls 106. Generally horizontal partition 104 may be contiguous ormay have openings penetrating some or most of its surface. Verticalsidewalls 106 are spaced wide enough apart to allow food preparationdevice 102 to telescope within vertical sidewalls 106.

FIG. 1 shows when food preparation device 100 is telescoped into thedeep concavity defined by sidewalls 106 and generally horizontalpartition 104. In this position the combination of food preparationdevice 100 and base 102 takes up little more space than food preparationdevice 100 alone. This compact configuration may make shipping andstorage easier.

FIG. 2 shows food preparation device 100 telescoped into base 102, withbase 102 being flipped over from the position for it shown in FIG. 1 sothat food preparation device 100 telescopes into the shallow concavitydefined by sidewalls 106 and generally horizontal partition 104. In thisposition pour spout 108 is elevated to allow taller liquid collectingvessels such as illustrative glass 110 to sit below and receive liquidfrom pour spout 108 (FIG. 2).

FIG. 3 shows food preparation device 100 lifted above base 102 with base102 flipped over 112 to the position shown in FIG. 2.

Snaps or latches may be used to hold base 102 to food preparation device100 in either or both of the compact and extended positions. Generallyvertical sidewalls 106 may be of various plan configurations includingcylindrical as shown, as well as other peripheral shapes such as, by wayof nonlimiting examples, square, rectangular, triangular or otherregular or irregular shapes. Likewise, the peripheral plan shape of foodpreparation device 100 which telescopes into base 102 may be varied tofit within such different shaped bases.

Exemplary Preferred Embodiment Two

FIGS. 4 through 6 illustrate adjustable height base 114 used to elevateand lower food preparation device 116. As shown in FIG. 6, base 114includes helical slots 118 and 120 which penetrate through generallyvertical sidewalls 122. At the top of helical slots 118 and 120 are twofinger grips which mirror each other, and only one of which, finger grip124, is shown. As is shown in FIG. 6 as well, food preparation device116 also has finger grip 126, which has a counterpart which isreplicated on the opposite side of food preparation device 116.

As shown in FIGS. 4 and 5, food preparation device 116 telescopes withinadjustable height base 114. As also shown in FIGS. 4 and 5, finger grip126 projects through helical slot 118, and, not shown, its opposite sidecounterpart projects through helical slot 120. When finger grip 126 issqueezed 127 toward finger grip 124, and their opposite sidecounterparts are simultaneously squeezed toward one another, foodpreparation device 116 rotates and rises causing food preparation device116 to be elevated from its lower position which is shown in FIG. 4, toits upper raised position shown in FIG. 5. This in turn raises pourspout 128 to its upper position as shown in FIG. 5 allowing tallerliquid collecting receptacles such as exemplary glass 130 shown in FIG.5 to be placed beneath pour spout 128.

Downward facing detents at the top of helical slots 118 and 120, bysupporting finger grip 126 and opposite side counterpart, hold foodpreparation device 116 in its upper position.

This preferred embodiment offers simple two-handed operation and allowsbase 114 to be continuously integrated with food preparation device 116.

Finger grip 126 may be disengaged from helical slot 118 by pushing itinward. This is also true for their opposite counterparts. This allowsbase 114 to be separated from food preparation device 116 for cleaningor other purposes.

Exemplary Preferred Embodiment Three

FIGS. 7 through 9, and including FIG. 9 enlargement 9A, show anotherpreferred embodiment. Here, food preparation device 132 telescopesinside of, and raises and lowers vertically within, base 134 allowingtaller liquid collecting receptacles, such as exemplary glass 136 to beplaced below pour spout 138. Latch actuation button 140 is biasedoutward and rides within slot 142. This arrangement is imaged on theopposite side of base 134 and food preparation device 132 where a latchactuation button which is not shown rides within slot 144. Foodpreparation device 132 is raised within base 134 by finger pressurepulling latch actuation button 140 toward finger rest 146 andsimultaneously doing the same action with the latch actuation button notshown and finger rest 148. Latch claws 150 grip detents on the interiorof sidewalls 152 to hold food preparation device 132 in its raisedposition. Pressing in on latch actuation button 140 and the opposinglatch actuation button not shown located on the opposite side, causeslatch claws 152 to become disengaged from detents on the interior ofsidewalls 152, and thus allows food preparation device 132 totelescopically descend within base 132 to the more compact configurationshown in FIG. 7. This may aid in storage. Food preparation device 132may be lifted free of base 134 for cleaning or other purposes by liftingit out of base 134.

Exemplary Preferred Embodiment Four

FIGS. 10 through 12, and including FIG. 12 enlargement 12 a, showanother embodiment which raises and lowers food preparation device 154within base 155 so that in its raised position pour spout 156 can beraised above tall liquid collecting vessels, such as exemplary glass158; and in its lowered position shown in FIG. 10 it can be made morecompact for storage, shipping, or other purposes. Food preparationdevice 154 is raised within base 155 by finger pressure pulling latchactuation button 160 toward finger rest 162 and simultaneously doing thesame action with the latch actuation button not shown and finger rest164. Latch claws 166, including 3 other symmetrically mounted latchclaws not shown, grip detents 170 on the interior of sidewalls 168 tohold food preparation device 154 in its raised position. Pressing in onlatch actuation button 160 and the opposing latch actuation button notshown on the opposite side, causes latch claws 166 disengaged from gripdetents 170 on the interior of sidewalls 168, and thus allows foodpreparation device 154 to telescopically descend within base 132 to themore compact configuration shown in FIG. 10. This may aid in shippingand storage. Food preparation device 154 may be freed from base 155 forcleaning or other purposes by lifting it out of base 155.

The plan cross-section where food preparation device 154 telescopicallyoverlaps base 155 may be of any of many different geometries. Theseinclude not only the rectangular cross section shown, but also otherregular and irregular shapes including, but not limited to: circular,elliptical, polygonal, and any other appropriate shape.

Exemplary Preferred Embodiment Five

FIG. 13, in FIGS. 13a, 13b, and 13c which are enlargements of a portionof FIG. 13, show a preferred embodiment for a valve controlled liquiddispensing spout. Here, liquid dispensing chute 172 pivots up and down182, 184 on pins 174 and 176 which are disposed within pivot holes 178and 180. Downward pivoted chute movement 184 may be initiated by aliquid collecting vessel, such as by way of a nonlimiting example, aglass, pressing inward 186 against actuation lever 188, or it may beinitiated by putting downward pressure on the extended outer end ofchute 172, as a non-limiting example, using a finger.

Downward pivoted chute movement 184 results in pliable plug 190unplugging from plughole 192 and thus allowing liquid to escape fromliquid containment vessel 194 through plughole 192.

Upward pivoted chute movement 182 may be initiated with upward 182pressure on the extended outer end of chute 172, as a nonlimitingexample, using finger pressure or the upward movement of a rim of aliquid collecting vessel. Such upward pivoted chute movement 182 has aresult of pushing pliable plug 190 into plughole 192 and thus blockingthe passage of liquid through plughole 192 and thus closing the valveformed by plug 190 and plughole 192.

By rotationally leveling chute 172 and by stopping liquid flowing intoit, dripping from chute 172 after it stops dispensing is terminatedalmost immediately, thus saving the time normally spent waiting fordripping to stop.

This embodiment offers user convenience by both using finger movement,and alternatively using movement of the upper rim of a liquid collectingvessel, to initiate and stop the flow of liquid from the embodiment'sliquid dispensing chute.

Exemplary Preferred Embodiment Six

FIG. 14 and FIGS. 14a, 14b, and 14c which are enlargements of a portionof FIG. 14, show another preferred embodiment for a valve controlledliquid dispensing spout.

In this preferred embodiment food preparation device 196 has liquiddispensing outlet 198, which is comprised of slide 200 which slides up206 and down 208 in front of the first outlet orifice 202 which islocated on the front the main body of food preparation device 196. Slide200 has second outlet orifice 204 penetrating front to back through it.

First outlet orifice 202 has circumferential pliable seal 210 completelysurrounding its periphery.

Circumferential pliable seal 210 forms a liquid tight barrier againstthe back of slide 200. When slide 200 is in its full up position asshown in FIG. 14a , second outlet orifice 204 is completely abovecircumferential pliable seal 220 resulting in the lower portion of slide200 forming a liquid tight seal across first outlet orifice 202, andtherefore shutting off the flow of any liquid through first outletorifice 202.

When slide 200 is lowered 208 to its lower position as shown in FIG. 14b, second outlet orifice 204 is directly in front of the first outletorifice 202, and therefore allows the flow of liquid through liquiddispensing outlet 198.

Finger grip 212 allows slide 200 to be manually raised 206 and lowered208. In addition, when slide 200 is in its lowered position, as shown inFIG. 14b , the rim of a liquid collecting vessel which liquid dispensingoutlet 198 is dispensing into can contact bottom portion 214 of secondoutlet orifice 204 and push slide 200 upward 206 to the positioned shownin FIG. 14a , and consequently shut off the flow of liquid throughliquid dispensing outlet 198. This is a convenience for the user.

Ears 216 and 218 may be manually pushed toward each other to disengageslide 200 from the main body of food preparation device 196 for cleaningor other purposes.

Exemplary Preferred Embodiment Seven

FIG. 15, and including enlargements of FIG. 15, FIG. 15a , FIG. 15b ,and FIG. 15c , show a preferred embodiment of a liquid dispensing outlet220.

Food preparation device 222 includes liquid collection vessel 224 withdispensing outlet 220 on its forward lower face. As shown in FIGS. 15a,15b, and 15c , dispensing outlet 220 includes slide 226 and alsoincludes first liquid dispensing outlet orifice 228 located on thebottom portion of liquid collection vessel 224.

Circumferential pliable seal 230 surrounds first liquid dispensingorifice 228 and forms a liquid tight seal between slide 226 and thecircumference of first liquid dispensing orifice 228. Slide 226 includessecond liquid dispensing outlet orifice 232 which penetrates top tobottom through slide 226.

When slide 226 is pushed fully in, as shown in FIG. 15a , only thenon-penetrated part of slide 226 is in contact with circumferentialpliable seal 230, thus preventing liquid from passing through dispensingoutlet 220.

When slide 226 is pulled fully outward, as shown in FIG. 15b , secondliquid dispensing outlet orifice 232 is directly below first liquiddispensing outlet orifice 228, thus forming a continuous opening whichallows the flow liquid through dispensing outlet 220.

To turn on and off the flow liquid through dispensing outlet 220, slide226 may be pulled out 234 and pushed in 236 manually using finger grip238.

Slide 226 may also be pulled out 234 and pushed in 236 using downwardprotruding member 240 to contact the upper rim of a liquid collectioncontainer placed below dispensing outlet 220. Here movement of the upperrim of the liquid collection container while pushing or pulling againstdownward protruding member 240 may move slide 226 from and to theposition shown in 15 a, where no liquid passes through outlet 220, fromand to the position shown in FIG. 15b , where liquid may pass throughoutlet 220. This may be a convenience for the user.

Exemplary Preferred Embodiment Eight

FIGS. 16, 17, and 18 as well as FIGS. 16 enlargements, FIG. 16a , FIG.16b , and FIG. 16c , show a preferred embodiment for a liquid outputpassage. Liquid output passage 242 includes partially cylindricalpivoted cover 244 which conforms to and covers the outside of liquidoutput passage base 246 which has a partial cylindrical face which ispenetrated by first output orifice 248. Orifice 248 is surrounded bycircumferential pliant seal 250 which seals its periphery liquid tightagainst the inside face of pivoted cover 244. Pivoted cover 244 ispenetrated by second outlet orifice 252.

When pivoted cover 244 is pivoted upwards 254, as shown in FIGS. 16a and18, only the non-penetrated portion of pivoted cover 244 is sealedagainst circumferential pliant seal 250, and therefore liquid is notallowed to pass through liquid output passage 242. When pivoted cover244 is pivoted downwards 256, as shown in FIGS. 16b and 17, secondoutput orifice 252 is aligned in front of first output orifice 248, andtherefore liquid is allowed to pass through liquid output passage 242.

Up 254 and down 256 movement of pivoted cover 244 may be accomplished byfinger pressure against cover 244. It may also be accomplished using therim of a liquid collection vessel which liquid output passage 242 isfilling, by pushing the rim against projection 258, or againstprojection 260. This flexibility of actuation methods may be aconvenience for the user.

Lip 262 on the output side of second outlet orifice 252 helps to stopdripping as soon as pivoted cover 244 is moved to its raised positionshown in FIGS. 16a and 18.

Exemplary Preferred Embodiment Nine

FIGS. 19, 20, and 21, as well as FIG. 19 enlargements, FIG. 19a , FIG.19b and FIG. 19c , show a preferred embodiment of a liquid outletpassage 264 which is similar to that shown in FIGS. 16 through 18 exceptprojection 260 has been minimized. Similar appearing parts performsimilar functions.

In this preferred embodiment projection 266 is contacted when pivotedcover 268 is moved up 270 and down 272 under pressure from movement of aliquid collection vessel rim.

Exemplary Preferred Embodiments Ten, Eleven, Twelve, and Thirteen

FIGS. 22 through 28 show 4 preferred embodiments for a centrifugaljuicer shredding disc. These all share on the outer portions of theshredding discs, shredding elements which may be similar to those foundin many of today's centrifugal juicers with different patterns of upwardfacing sharpened elements. The preferred embodiments differ in theshredding element found at each disc's centers. Here, raised shreddingelements provide a combination of food shredding movement and foodshredding chopping by engaging the food with asymmetric members.

FIGS. 22 and 23 show a preferred embodiment. Referring to FIGS. 22 and23, diagonally disposed triangular blade 274 is located with its baseadjacent to the center of shredding disc 276. Each of the upwardextending edges on blade 274 may be dull or may be beveled forsharpness.

As shredding disc 276 rotates 278 it carves a portion of food descendingonto the center of shredding disc 276. Simultaneously, because blade 274is offset to disc 276 itself, it moves the food latterly in a vibratingmotion across the top of disc 276. Both of these actions help todisintegrate food.

FIGS. 24 and 25 show a preferred embodiment. Referring to FIGS. 24 and25, bent triangular blade 280 is mounted near the center of shreddingdisc 282. Each of the upward extending edges on blade 280 may be dull ormay be beveled for sharpness.

As shredding disc 282 rotates 284 it carves a portion of food descendingonto the center of shredding disc 282. Simultaneously, because blade 280is offset to disc 282 itself, it moves the food latterly in a vibratingmotion across the top of disc 282. Both of these actions help todisintegrate food.

FIGS. 26 and 27 show a preferred embodiment. Referring to FIGS. 26 and27, short pin 286 and long pin 288 are mounted adjacent to the center ofshredding disc 290.

As shredding disc 290 rotates 292 it shreds a portion of food descendingonto the center of shredding disc 290. Simultaneously, because short pin286 and long pin 288 are mounted asymmetrically on disc 290, they movethe food latterly in a vibrating motion across the top of disc 282. Bothof these actions help to disintegrate food.

FIG. 28 shows preferred embodiment shredding disc 294 with centralvertically disposed triangular blade 298. Each of the edges on blade 298may be dull or beveled for sharpness.

As shredding disc 294 rotates 296 it shreds a portion of food descendingonto the center of shredding disc 294. Simultaneously, because blade 298is offset to disc 294, it moves the food latterly in a vibrating motionacross the top of disc 294. Both of these actions help to disintegratefood.

Exemplary Preferred Embodiment Fourteen

FIG. 29, and enlargements of FIG. 29, FIG. 29a and FIG. 29b , show apreferred embodiment of centrifugal juicer 300.

Here, 2 interchangeable filter cones, 302, 304, each with a differentfilter mesh, 306, 308 respectively, are supplied with juicer 300. Byproviding more than one filter cone, each filter cone having a differentporosity filter mesh, extracted juices may be provided with more or lesspulp. This may be an important user feature as demonstrated by thegrocery store orange juice market which has individual sections forjuice with no pulp, some pulp, and heavy pulp.

Exemplary Preferred Embodiment Fifteen

FIGS. 30 through 38, including FIG. 38 enlargement, FIG. 38a ,illustrate a preferred embodiment of the subject application. Herecentrifugal juicer embodiment 309 is shown with, pusher plunger face 310which is pivotally 311 mounted to lever/handle 312, which in turn ispivotally 314 mounted to juicer lid 316.

Disposed directly adjacent to pusher plunger face 310 and connected toit, is wiper 318. FIG. 35 shows plunger face 310 fully lowered. FIG. 36shows embodiment 309 with lid 316 not shown for clarity of viewing innercomponents, and pusher plunger face 310 is shown also fully lowered asin FIG. 35. As shown in FIGS. 35 and 36, wiper 318 wipes against innerface 320 of truncated conical filter 322 when pusher plunger face 310 isfully lowered. In operation, when truncated conical filter 322 ispowered and spinning, contact of wiper 318 against inner face 320 oftruncated conical filter 322 cleans face 320. Wiper 318 may be: a brush,a stiff or flexible blade, one or more rigid or flexible segmentedblades, or may be made using other appropriate construction.

Automatically cleaning inner filter face 320 can be a major advantage toan embodiment user, first, because it makes simple what is normally atedious and difficult job to do, and second, because it improves theefficiency of filter 322 by wiper 318 cleaning debris off inner face 320which would otherwise clog filter 322.

Pusher plunger face 310 traverses generally vertically within feed chute324. FIGS. 30 and 31 show pusher plunger face 310 in its fully raisedposition. FIGS. 32 and 33 show pusher plunger face 310 partiallylowered. In FIGS. 34 through 37 pusher plunger face 310 is fullylowered. FIG. 38 is a partially exploded perspective view with pusherplunger face 310 fully lowered.

When pusher plunger face 310 is fully raised, as illustrated in FIGS. 30and 31, a safety interlock switch is activated by cam 326. Cam 326 islocated at the base of lever handle 312 directly adjacent to pivot 314.The activated safety interlock switch shuts off power to embodiment309's motor and will not allow operation of embodiment 309's motorunless pusher plunger face 310 is at least lowered to a predeterminedposition.

Thus, unless pusher plunger face 310 is at least partially lowered,there is no safety hazard posed from a hand extending through feed chute24 and coming in contact with a spinning shredder disc.

When comparing embodiment 309 to other centrifugal juicers, this allowsan usually large feed chute, approaching the full diameter of embodiment309's shredder disc, because hand entry into the feed chute isprevented, not by the diameter of the feed chute, or by its length as inother centrifugal juicers, but rather by the necessity for pusherplunger face 310 to be partially lowered and thus partially blocking theentry to feed chute 324 before embodiment 309's motor can be activated.

Embodiment 309 also shows the use of the elevated base shown in FIGS. 10through 12 and descriptions related to those figures given herein.

Embodiment 309 has internal liquid reservoir 328 which can be viewedthrough reservoir 328's generally vertical side walls 330 which have atleast a translucent section through which the contents of reservoir 328may be viewed to prevent overflowing reservoir 328, and/or to see thequality, content, and/or condition of the juice or other liquid withinreservoir 328, and/or for any other reason. Reservoir 328 receivesliquid which has passed through truncated conical filter 322.

Embodiment 309 uses output chute/valve 332 which is similar to thedevice illustrated in FIGS. 13, 13 a, 13 b, and 13 c herein anddescribed in the descriptions herein related those figures. Use of anoutlet which can be fully closed through valve action is fundamental tothe operation of internal liquid reservoir 328. By way of nonlimitingexamples, several outlets which can be fully closed are shown in FIGS.13 through 21 herein, and described in related specification thereto.

Internal liquid reservoir 328 allows juicing without requiring a glassor other liquid collection vessel being placed under output chute/valve332. This may be an advantage to the user who does not have to juggleglasses or other liquid collection vessels while simultaneously placingfruits, vegetables or other foods into embodiment 309.

A problem with centrifugal juicers is that usually the juice theyprovide separates within a few minutes after it is produced. Thisseparation changes both the appearance and taste of the fresh juice. Toprevent this, embodiment 309 has truncated cone mixing element 334 whichis attached to the bottom of inverted truncated conical filter 322, androtates with it when embodiment 309's motor is activated.

When rotating, element 334 mixes liquids within reservoir 328, thusovercoming the problems of juice and/or liquid separation.

The mixing ability of truncated cone mixing element 334 may be enhancedthrough the use of texturing or contouring or penetrating the innerand/or outer faces of element 334. By way of nonlimiting examples,element 334 is illustrated with holes 336 penetrating it surface, ribs338 disposed on its outer surface, and contoured lower rim 340 (FIG.36). Any combination of any or all of these elements, as well as amultitude of other devices such as, by way of additional nonlimitingexamples, rippling or bending or adding propeller-like blades to thesurface(s) of element 334, would suffice to enhance element 334's mixingaction.

Exemplary Preferred Embodiment Sixteen

FIGS. 39 through 42 show preferred embodiment centrifugal juicer 368with feed chute 370 which rocks front 360 to back 362 and side 364 toside 366, or any diagonal between, to more efficiently shred food fedthrough chute 370 by allowing movement of food across shredding plate372.

Feed chute 370 is held in place by 4 pins (of which pins 374, 376, and378 are shown) which engage inside of 4 loosefitting openings 380, 382,384, and 386. The loose fit between the 4 pins and the 4 openings allowsfeed chute 370 a limited degree of rocking motion as shown by theghosted images in FIGS. 41 and 42 which in turn allows food fed throughfeed chute 370 to be exposed to shredding plate 372 a small portion at atime rather than exposing the full cross section of food being fedthrough feed chute 370 to shredding plate 372 all at once.

FIGS. 39 through 41 are perspective views each taken from identicalviewpoints. FIG. 42 is a front x-ray view of centrifugal juicer 368.

FIG. 62 is a perspective taken from the same viewpoint as FIG. 60. FIG.62 shows exemplary food 478 being inserted into pliable vertical ribinsert 474, and shows how inward directed pliable vertical ribs 470deflect, direct, and hold exemplary food 478 while it drops down ontothe shredder disc of embodiment centrifugal juicer 468. FIG. 63 is adirect overhead view of FIG. 62 depicting exemplary food 478 therein.

Inward directed pliable vertical ribs 470 allow a large feed openingwhile simultaneously impeding hand entry into feed chute 472. Thisoffers users both a benefit by having a feed opening which can acceptlarge articles of food without the necessity to cut them into smallerpieces, and a safety benefit by preventing accidents caused by usercontact with the shredder blade.

Inward directed pliable vertical ribs 470 also block food particlescreated and propelled by embodiment 468's shredder disc from exiting thetop of feed chute 472. This too is a safety benefit to the user. It alsohelps reduce messes on countertops, users, and adjacent floors.

Exemplary Preferred Embodiment Twenty-Three

Preferred embodiment centrifugal juicer 480 is shown in FIGS. 64 through67. Preferred embodiment 480 has segmented pliable sheet cover 482covering entry 484 to feed chute 486.

Segmented pliable sheet cover 482 is comprised of multiple pliablesheets 488 which are in close proximity and are able to separate andbend to allow passage of articles of food through cover 482, as shown inFIG. 67, while being able to block entry 484 when food articles are notpassing through cover 482, as shown in FIG. 66.

A multitude of segment patterns is possible besides the radiatingpattern shown in FIGS. 64, 66 and 67. As a nonlimiting example,referring to FIGS. 90 and 90 a, a fishbone type of pattern is shown asan alternative.

In this disposition, segmented pliable sheet cover 482 blocks entry484 to feed chute 486. This helps prevent accidents due to user contactwith the shredder disc and other internal moving parts of preferredembodiment 480. It also helps to prevent particles of food which havebeen created by the shredder disc of preferred embodiment 480 from beingpropelled by the shredder disc back out of entry 484 of feed chute 486.Food particles escaping entry 484 might cause countertop and usermesses, and might create a safety hazard from food particle impact.

FIG. 67 is an overhead perspective view of preferred embodiment 480taken from the same viewpoint as FIG. 66. FIG. 67 shows exemplary foodarticle 496 being inserted through segmented pliable sheet cover 482.While food article 496 is passing through segmented pliable sheet cover482 it is held by segments 498 of segmented pliable sheet cover 482which helps to stabilize and control food article movement. This isparticularly true of the elongated shape foods such as carrots andcelery, where segments 498 help to control rotational and vibrationalmovement.

Segmented pliable sheet cover 482 may be made of any of variety ofmaterials including, by way of nonlimiting examples: silicon or neoprenerubber, or various elastomers.

Exemplary Preferred Embodiment Twenty-Four

FIGS. 68 through 71 and including FIG. 71 enlargement, 71A, show apreferred embodiment, centrifugal juicer embodiment 342. Embodiment 342adds an additional juice extracting step to its juicing method.

Initially food is lowered through feed chute 344 onto shredding disc 346where the food is first disintegrated and, driven by centrifugal force,food escapes under lower edge 348 of feed chute 344.

Feed chute 344 is generally cylindrical except for vertical protrusion350 which runs the full height of chute 344. Protrusion 350 helps tostabilize food fed into chute 344 and prevent the food from spinningand/or having other undesirable motions.

Once escaping under lower edge 348 of feed chute 344, food particles,driven by centrifugal force, move up the inside of inverted truncatedcone filter 352.

Part way up the inside of inverted truncated cone filter 352, annularconverging wall 354 squeezes the food particles against the inside ofinverted truncated cone filter 352 resulting in additional liquid beingextracted from the food particles.

One or more roughened surfaces may aid in this additional liquidextraction process. As a nonlimiting example, shredder plates 356 withsharpened protrusions on their inward facing surfaces might be mountedon the inside of inverted truncated cone filter 352. Such plates could,by way of nonlimiting examples, be larger or smaller or of greater orlesser number than those illustrated in FIG. 70, and might even extendthe full inner diameter of inverted truncated cone filter 352. Theymight also be of different shape than those illustrated in FIG. 70 suchas, by way of nonlimiting examples, round or triangular. Their roughenedsurfaces might be sharp points, or might be linear or curved blade-likeprotrusions or might be textured like sandpaper.

As another nonlimiting example of such roughened surfaces, shredderplate 358 might be mounted on annular converging wall 354 as illustratedin FIG. 69. Again, by way of nonlimiting examples, such a plate could belarger or smaller or of greater number than that illustrated in FIG. 70,and might even extend the full outer diameter of annular converging wall354. It might also be of different shape than that illustrated in FIG.69, such as, by way of nonlimiting examples, round or triangular. Itsroughened surface might be sharp points, or might be linear or curvedblade-like protrusions or might textured like sandpaper.

Shredder plates 356 and 358 further disintegrate food particles passingthrough them and thereby extract additional liquid from the foodparticles they contact.

Exemplary Preferred Embodiment Twenty-Five

FIGS. 72 through 76 show preferred embodiment centrifugal juicer 500.Preferred embodiment 500 has large feed chute 502 extending upward fromlid 504. Large feed chute 502 can have small feed chute 506 inserted 508into it. In turn, small feed chute 506 can have pusher plunger 510inserted 512 into it.

Activation rib member 514 on the side of small feed chute 506 passesthrough opening 516 on safety interlock switch stalk 518 when small feedchute 506 is being inserted 508 into large feed chute 502. Activationrib member 514, when passing through opening 516, activates safetyinterlock switch 520, which consequently permits embodiment centrifugaljuicer 500's motor to operate. As illustrated, the safety interlockswitch is located at the top of safety interlock switch stalk 518adjacent to opening 516. However, the safety interlock switch could belocated elsewhere, as by way of a nonlimiting example, be located insidethe lower housing of preferred embodiment centrifugal juicer 500 and beactivated through mechanical means feeding through safety interlockswitch stalk 518.

Having safety interlock switch 520 which is activated by insertion ofsmall feed chute 506 into large feed chute 502, means that large feedchute 502 can be much larger in cross-section than a comparable feedchute which had to prevent through its feed chute length width anddepth, accidents associated with users touching through the feed chute,dangerous internal parts, such as shredder discs. Having a larger issuemay result in less food preparation time being needed because foods donot have to be cut a small in order to fit through the chute.

In use, the user inserts food articles into large feed chute 502 and,using small feed chute 506 possibly in combination with pusher plunger510 as a pusher plunger, pushes the inserted food through large feedchute 502 onto preferred embodiment 500's shredder disc where it isjuiced. Insertion of small feed chute 506 into large feed chute 502activates safety interlock switch 520 which causes preferred embodiment500's motor to be turned on and juicing to take place.

For smaller foods that don't require the feed chute size of large feedchute 502, small feed chute 506 may be inserted into large feed chute502 and preferred embodiment centrifugal juicer 500 used in aconventional manner without relying for safety on safety interlockswitch 520 to turn off and on preferred embodiment 500's motor whilefeeding food articles into preferred embodiment 500.

Large feed chute 502 is mounted on lid 522 by trunk latches 524 and 526.Securing trunk latches 524 and 526 causes not only the securing of largefeed chute 502 to lid 522, but also causes lid 522 to be secured onlower body 528 of preferred embodiment 500.

FIGS. 77 through 81 show preferred embodiment centrifugal juicer 530.Preferred embodiment 530 uses gripping pusher plunger 532 to grasp foodarticles being fed into, or already fed into, preferred embodiment 530.This grasping feature helps more positively feed food articles intopreferred embodiment 530, and helps reduce undesirable food movement,including rotation and vibration, which may be encountered while feedingfood articles into preferred embodiment 530. Gripping pushing plunger532 may also be used like a conventional pushing plunger to push anddirect foods onto preferred embodiment 530's shredder plate.

FIG. 77 is a perspective view of preferred embodiment 530 showingexemplary food article 534 being pushed through segmented pliable sheetfeed chute cover 536. Food articles may be introduced into preferredembodiment 530 in this manner, or by feeding the food articles directlyinto feed chute 538 when no pusher plunger is in place, or they may befed in using the gripping feature of gripping pusher plunger 532 to holdand lower in a controlled fashion food articles.

Preferred embodiment centrifugal juicer 530 uses a safety interlockswitch as described earlier herein to prevent accidental user contactwith the spinning shredder disc of preferred embodiment 530.

FIGS. 82 through 84 show preferred embodiment centrifugal juicer 552which is similar to preferred embodiment centrifugal juicer 530described earlier herein except gripping pusher plunger 554 and feedchute 556 are constructed differently than their counterparts found onpreferred embodiment 530. Here, there is only one gripping plate 558which swings on pivots about vertical axis 568 inside outer walls 560 ofgripping pusher plunger 554.

Preferred embodiment centrifugal juicer 552 offers similar benefits topreferred embodiment centrifugal juicer 530.

Gripping plate 558 is moved to its in position as shown in FIG. 82, andshown by ghosted lines 572 in FIG. 83, through finger pressure on rearwall 576 of gripping plate 558. As shown in FIG. 84, rear window 578through outer walls 560 allow finger access to rear wall 576 of grippingplate 558.

Gripping plate 558 is moved to its out position as shown by solid lines570 in FIG. 83 under bias from internal springs. FIG. 82 is aperspective view taken from below and in front of preferred embodiment552. FIG. 82 shows gripping pusher plunger 554 holding exemplary foodarticle 574 with gripping plate 558 in its pivoted in or grippingposition.

FIG. 83 is a perspective view of gripping pusher plunger 554 taken frombelow and in front of gripping pusher plunger 554. FIG. 83 showsgripping plate 558 with solid lines 570 in its pivoted out position, andit shows gripping plate 558 in ghosted lines 572 in its pivoted inposition holding exemplary food article 574 which is also ghosted, inits grasp.

FIG. 84 is a perspective view of gripping pusher plunger 554 taken fromabove and behind gripping pusher plunger 554. It, like FIG. 83, showsexemplary food article 574 being gripped by gripping pusher plunger 554in its pivoted in position.

Gripping pusher plunger 554 is generally cylindrical and has generallycylindrical gripping plate 558 pivoted 562 forward 564 and rearward 566on vertical axis 568 inside pusher plunger 554's outer walls 560.

Gripping plate 558 has teeth 580 on its interior surface to aid ingripping food articles. Other texturing might be used to hold foodarticles such as, by way of nonlimiting examples, a sandpaper likefinish, small spikes, waffle patterns, etc.

Also portions of the interior of outer walls 560 might be textured in asimilar manner to aid in gripping food articles.

FIGS. 85 and 86 show preferred embodiment centrifugal juicer 582 whichhas feed chute 584 that has pivots 592 to allow it to rotate up 588 to ause position as shown in FIG. 85, and down 590 to a more compactshipping and storage position, as shown in FIG. 86.

Exemplary Preferred Embodiment Twenty-Nine

FIGS. 87 through 90 including FIG. 90 enlargement, FIG. 90a , showpreferred embodiment blender 594.

FIG. 87 is a perspective of preferred embodiment blender 594. FIG. 88 isan x-ray perspective taken from the same viewpoint as FIG. 87. FIG. 89is a right side view of preferred embodiment blender 594 with variousinternal components including, but not limited to, inclined motor 596,shown in ghosted lines. FIG. 90 is an exploded perspective view ofpreferred embodiment blender 594. FIG. 90a is an enlarged this of aportion of FIG. 90 as indicated in FIG. 90.

Preferred embodiment blender 594 has inclined motor 596 mounted to thebottom of blending container 598 using motor mount 600 which is disposedgenerally at right angles to inclined motor drive shaft 602. Blendingcontainer 598 has open bottom 604 which attaches blade mount 606 androtary blade 608 which is rotationally mounted to blade mount 606.

Blending container 598 has a generally vertical orientation. Located onforward face 610 of blending container 598 are valve 612 and pour spout614. Mounted between valve 612 and pour spout 614 is first filter mesh616. Second filter mesh 618 is part of preferred embodiment blender 594and has a filter mesh which allows coarser solids through it than isallowed by first filter mesh 616. Thus the amount of solids, such aspulp, contained in liquids, and semi-liquids dispensed through valve 612and pour spout 614 can be controlled by substituting different filtermeshes with one another, such as substituting first filter mesh 618 withsecond filter mesh.

Filter meshes 616 and 618 are each U-shaped in plan view and are mountedinto forward blending container channel 620. Pour spout 614 is mountedat the top of or blending container channel 620 and valve 612 is mountedat the bottom of forward blending container channel 620. Thus in orderfor liquid to exit blending container 598 through either valve 612 orpour spout 614, the liquid must pass through a filter mesh, such asfirst filter mesh 616 or second filter mesh 618.

Mounted on the back of blending container 598 is handle 622 which helpsin manipulating blending container 598. Such manipulation may include,but is not limited to, mounting and dismounting blending container 598from blender base 624, as well as pouring liquid from pour spout 614 andplacing blending container 598 in a refrigerator or elsewhere.

Channels 626 hold blending container 598 as do mounting detent 628, toblender base 624. Together they mount blending container 598 in agenerally vertical orientation. Frustum conical drive coupling 630couples inclined motor 596 to blade 608 and allows, along with channels626 and mounting detent 628, blending container 598 to be mounted anddismounted from blender base 624 through vertically lifting or droppingblending container 598 away from or onto blender base 624. This in turnmay simplify and make more intuitive mounting and dismounting blendingcontainer 598 from blender base 624.

Having inclined motor 596 being mounted at angle to the generallyvertical orientation of blending container 598 offers several potentialadvantages. As a nonlimiting example, the bulk of the weight ofrelatively heavy inclined motor 596 is more behind the center of mass ofblending container 598 than if inclined motor 596 were not inclined,which helps prevent preferred embodiment blender 594 from fallingforward. By lessening the need for protruding forward facing countertopsupports or extended forward facing outlet valves, this potentiallysaves countertop space.

As another nonlimiting example, the spatial mass of inclined motor 596is also more behind the center of spatial mass of blending container 598than if inclined motor 596 were not inclined, which allows valve 612space to be located more under the center of mass of blending container598 rather than protrude outward. This also potentially saves countertopspace.

As another nonlimiting example, in combination with the configuration ofblending container 598, the inclination of blade 608 may improve theflow of blending materials within blending container 598, at leastbecause a vortex created by blade 608 will be inclined into forward face610 of blending container 598 and be deflected. This can reduce blendingineffectiveness caused by vertical blending vortexes.

FIG. 90 shows lid 632 which utilizes segmented pliable sheet cover 634which has radial segmentation pattern 636. It also shows lid 638 whichhas fishbone segmentation pattern 640. FIG. 90a shows how fishbonesegmentation pattern 640 allows exemplary food article 642 to passthrough it. These patterns demonstrate by way of nonlimiting examples,that segmented pliable sheet covers can be made in many geometricsegmentation forms.

FIGS. 91 through 93 show preferred embodiment blender 644 with grippingpusher plunger 646. FIG. 91 is a perspective view of gripping pusherplunger 646 with its open arm non-grasping disposition shown in solidlines 648, and its clamping arm grasping disposition shown in ghostedlines 650.

FIG. 92 is a perspective view of preferred embodiment blender 644 withgrasping pusher plunger 646 ready to be inserted 654 through pliablesegmented sheet lid 652 into blending container 656.

FIG. 93 is a perspective view taken from the same vantage point as FIG.92, but after grasping pusher plunger 646 has been inserted intoblending container 656 through pliable segmented sheet lid 652.

Gripping pusher plunger 646 is comprised of a first arm 658 and a secondarm 660. First arm 658 is pivoted on its upper end on pivot point 662and on a second mirror image pivot point which is on the opposite sideof first arm 658 and not shown. Second arm 660 is pivoted on its upperend on pivot point 664 and on a second mirror image pivot point which ison the opposite side of second arm 660 and not shown.

Movement of first arm 658 and second arm 660 is controlled by fingergrip 666 located adjacent to pivot point 662 and by an opposing mirrorimage finger grip which is not shown and is located at the top of secondarm 660 adjacent to pivot point 664.

Inward finger pressure 668 on the two finger grips causes grippingpusher plunger 646 to move from its open arm nongrasping dispositionshown in solid lines in FIG. 91, to its clamping arm graspingdisposition shown in ghosted lines in FIG. 91.

First arm 658 and second arm 666 are spring biased 670 away from oneanother with internal spring. Relaxation of finger pressure against thetwo finger grips causes gripping pusher plunger 646 to move from itsclamping arm grasping disposition shown in ghosted lines in FIG. 91 toits open arm nongrasping disposition shown in solid lines in FIG. 91.

Gripping pusher plunger 646 can be used to insert food into preferredembodiment blender 644 as shown in FIGS. 92 and 93 and direct food whileit is in blending container 656. It can also be used as a conventionalblender plunger, similar to that found on VitaMix™ brand blenders.
